Jerry, That's true (it's also true if you accidentally IPL a test system using the production paging subsystem) that corrupting/losing critical DASD will cause z/OS to fall over. However, I believe the OP mentioned that the SEs were restarted as well. I don't recall if the z14 has internal battery backup for the SE's or not, but if not, IBM made (in my opinion) a mistake moving from laptops with internal batteries to 1u "pizza boxes" for the SEs without BBU. It sure smells to me like there was some kind of power issue that impacted both of the power feeds coming in to the z14.
